Routing Basics and Interfaces Quiz

Dynamic routing protocols operate by manually configuring routing tables for each router.

OSPF is a protocol that allows routers to dynamically learn about networks connected to them.

Static routes are indicated by the status code 'O' in the routing table.

The link-local address is used by IPv4 routing protocols to identify the next-hop router.

The routing entries for both IPv4 and IPv6 networks include information about the next-hop router's address.

The structure of an IPv6 routing table was influenced by the concept of classful addressing.

An IPv6 route entry formatted as 'C 2001:DB8:ACAD:1::/64 [0/0]' indicates a directly connected network.

The subnet mask for the route 192.168.12.0/30 uses a 30-bit mask.

The route entry 'R1# show ipv6 route' is an indication of the routing protocol being used.

Static routing is exclusively used in larger networks with multiple paths.

IPv6 routing tables are not formatted uniformly.

The administrative distance for directly connected routes is 0.

In OSPF, faster links are assigned higher costs compared to slower links.

EIGRP summary routes have an administrative distance of 20.

The next-hop address for an IPv6 route entry can be identified by the notation 'via FE80::2:C'.

EIGRP calculates a metric based solely on bandwidth.

RIP has a higher administrative distance than OSPF.

The entry 'OE2 ::/0 [110/1], tag 2' signifies a static route in IPv6.

Static routing can be used to explicitly define the path for a specific network.

Equal cost load balancing allows a router to use multiple paths to send packets equally when paths have the same cost.

A parent route may include several child routes with similar attributes.

Static routes cannot be used for load balancing in a network.

External BGP has an administrative distance of 200.

Dynamic routing protocols and static routes are mutually exclusive and cannot be used together.

Dynamic routing protocols automatically implement unequal cost load balancing.

OSPF has a higher administrative distance than IS-IS.

The longest match in a routing table is defined as the route with the least number of matching bits.

Directly connected networks are those that appear in the routing table due to active interfaces of the router.

Static routes can be useful for routing between stub networks.

Load balancing can increase the effectiveness and performance of a network.

The administrative distance for an internal EIGRP route is 90.

The metric used by OSPF is based only on cumulative distance.

A routing table can contain multiple exit interfaces for the same destination.

The best path in the routing table is defined as the shortest match.

For a route to match the destination IP address, a certain number of far-left bits must match.

The longest match is always the preferred route in the routing table.

In the example given, the destination IPv4 address is 172.16.0.0/26.

An IPv4 packet with the address 172.16.0.10 matches three routes in the routing table.

The prefix length indicates how many bits must match for a route to be considered valid.

The router would select the route 172.16.0.0/12 to forward the packet based on the longest match rule.

IPv6 addresses also utilize the concept of prefix length for routing.

The address 2001:db8:c000::99 is an example of an IPv4 address.

Matching bits are used to determine the best path in a routing table.
